Description

Technical Field

[0001] The utility model relates to the field of textile equipment machinery, and particularly relates to a support structure for a roller of a computerized flat knitting machine. Background Art

[0002] A computerized flat knitting machine pulls a fabric through rollers. The specific principle of the roller pulling the fabric is as follows: There are two sets of front and rear rollers. When the rollers rotate, the roller covers on the two rollers rotate towards each other, so as to realize the pulling of the fabric between the roller covers of the front and rear rollers.

[0003] In the prior art, the roller structure includes a roller tube, a bracket assembly, a limit support piece and a roller cover. The roller tube is rotationally fitted with the limit support piece, and the bracket assembly is fixed on the roller tube. During operation, the limit support piece is fixed, the roller tube rotates relative to the limit support piece, and the roller cover is driven by the bracket assembly to rotate towards or away from each other to realize the pulling of the fabric. Among them, a circular through hole is formed in the limit support piece, and each roller tube is divided into two sections at the limit support piece, and the two sections of roller tubes are connected by a connecting piece passing through the limit support piece. Thus, the roller tube can be supported by the limit support piece, and at the same time, a limit structure is arranged on the limit support piece to limit the rotation angle of the bracket assembly.

[0004] In the above roller structure, a bearing is installed in the through hole of the limit support piece to reduce the resistance during the relative rotation between the roller tube and the limit support piece. However, limited by the processing technology of the bearing housing and rollers, the existing bearings cannot be made very thin in the axial direction, and the thickness of the bearings is generally greater than the thickness of the limit support piece, resulting in too large a distance between the two sections of roller tubes on both sides of the limit support piece, and there is a large gap between the roller covers on the two roller tubes. The roller cover cannot apply force at the gap when pulling the fabric, resulting in poor consistency of the fabric force and affecting the aesthetics of the pulled fabric. Summary of the Invention

[0005] In order to solve the defect of poor consistency of the fabric force when the roller structure of the computerized flat knitting machine pulls the fabric in the prior art, the utility model provides a support structure for a roller of a computerized flat knitting machine.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] The utility model provides a support structure for a roller of a computerized flat knitting machine. The support structure is used to support a roller tube. The support structure includes a rotating shaft, a limit support piece and a support bushing; the limit support piece is used for being fixedly installed on the needle bed base of the computerized flat knitting machine. A connecting through hole is formed in the limit support piece. The support bushing is coaxially fitted in the connecting through hole. The limit support piece is sleeved outside the support bushing. The rotating shaft is inserted into the support bushing and the rotating shaft can rotate relative to the limit support piece;

[0008] The roller tube includes a first tube section and a second tube section. The first tube section and the second tube section are coaxially arranged on opposite sides of the limit support piece. One end of the rotating shaft extends out of the connection through-hole and is connected to the first tube section, and the other end of the rotating shaft extends out of the connection through-hole and is connected to the second tube section.

[0009] Further, a circumferential annular limit groove is formed on the outer side of the support bushing along the circumferential direction, and the inner wall of the connection through-hole is embedded in the limit groove.

[0010] Further, the support bushing includes a first limit ring, a connection sleeve and a second limit ring which are coaxially connected. The connection sleeve is arranged in the connection through-hole. The first limit ring and the second limit ring are respectively located on opposite sides of the connection through-hole, and the first limit ring and the second limit ring are spaced apart to form the limit groove.

[0011] Further, the first limit ring is fixedly connected to the connection sleeve. An annular step is arranged at one end of the connection sleeve away from the first limit ring, and the second limit ring is fitted to the annular step.

[0012] Further, the support structure further includes a wear-resistant sleeve. The rigidity of the wear-resistant sleeve is greater than that of the support bushing. The wear-resistant sleeve is coaxially sleeved outside the limit groove, and the outer side of the wear-resistant sleeve is in contact with the inner wall of the connection through-hole.

[0013] Further, the support bushing is made of plastic, and the wear-resistant sleeve is made of materials such as iron, stainless steel or copper.

[0014] Further, a bracket assembly is connected to the outer periphery of the roller tube, and a roller leather sleeve is sleeved outside the bracket assembly and the roller tube;

[0015] The bracket assembly is in contact with the upper side of the limit support piece. One side of the limit support piece facing the bracket assembly has a support surface. A stop portion is convexly provided at the outer edge of the support surface. The inner edge of the support surface slopes downward from the direction away from the stop portion to form a limit surface. The stop portion and the limit surface jointly limit the rotation range of the bracket assembly.

[0016] Further, the bracket assembly is provided with a swing groove, and the opening of the swing groove faces the limit support piece; the support surface is inserted into the swing groove and abuts against the bracket assembly.

[0017] Further, the upper end surface of the support surface is a flat straight surface, and the bottom wall of the swing groove facing the limit support piece is also a flat straight surface. The support surface is in close contact with the bottom wall of the swing groove.

[0018] Furthermore, a connecting seat is detachably connected to the bottom side of the limit support piece, and the limit support piece is fixedly connected to the knitting bed base through the connecting seat.

[0019] In summary, the present utility model has the following beneficial effects:

[0020] 1. For the support structure of the roller of the computerized flat knitting machine of the present utility model, the rotating shaft is supported by the limit support piece, and the first pipe section and the second pipe section of the roller tube are respectively connected to both sides of the rotating shaft, realizing the rotational support of the roller tube. Among them, a support bushing is installed in the connecting through hole of the limit support piece to replace the traditional bearing, and the rotating shaft passes through the support bushing. The support bushing is simple to process, and the axial thickness of the support bushing can be reduced, thereby reducing the gap between the first pipe section and the second pipe section. Furthermore, the gap between the two sections of roller leather sleeves connected to the outside of the first pipe section and the second pipe section is reduced, and the force consistency of the fabric during the pulling of the fabric is good, and the fabric forming is beautiful.

[0021] 2. A limit groove is arranged outside the support bushing, and the inner wall of the connecting through hole of the limit support piece is embedded in the limit groove, so that the limit support piece is axially limited on the support bushing, avoiding the support bushing from moving up and down on the limit support piece.

[0022] 3. The first limit ring and the second limit ring are respectively arranged on both sides of the limit support piece to form a limit groove to limit the limit support piece; the first limit ring is fixed to the connecting sleeve, and the second limit ring is matched with the annular step on the connecting sleeve. Therefore, when installing the support bushing, the connecting sleeve can be passed through the connecting through hole and then the second limit ring can be matched with the annular step, which is convenient for the connection between the support bushing and the limit support piece.

[0023] 4. A wear-resistant sleeve with relatively large rigidity is coaxially sleeved outside the support bushing. The support bushing is protected by the wear-resistant sleeve, so that the relatively thin limit support piece is not easy to wear and cut the support bushing, ensuring the service life of the support structure.

Detailed implementation manners

[0034] The present utility model will be further described below with reference to the accompanying drawings.

[0035] This embodiment discloses a support structure for a computer flat knitting machine roller. Referring to Figures 1 to 3 , the computer flat knitting machine roller 1000 includes a roller tube 100, a bracket assembly 200, and a roller leather sleeve 300. The outer periphery of the roller tube 100 is connected to the bracket assembly 200, and a roller leather sleeve 300 is sleeved outside the bracket assembly 200 and the roller tube 100. During use, two sets of computer flat knitting machine rollers 1000 are arranged in parallel and adjacent to each other. The rotation of the roller tube 100 drives the rotation of the bracket assembly 200 and the roller leather sleeve 300, so that the roller leather sleeves 300 of the two computer flat knitting machine rollers 1000 move towards each other to pull the fabric.

[0036] In this embodiment, the support structure 400 is used to support the roller tube 100. Referring to Figure 4 and Figure 5, the support structure 400 includes a rotating shaft 410, a limiting support piece 420, and a support bushing 430. The limiting support piece 420 is fixedly installed on the needle bed base of the flat knitting machine. The rotating shaft 410 is rotatably arranged on the limiting support piece 420 through the support bushing 430. The rotating shaft 410 is connected to the roller tube 100, so as to realize the support of the limiting support piece 420 for the roller tube 100, and at the same time enable the roller tube 100 to rotate relative to the limiting support piece 420.

[0037] In this embodiment, the limiting support piece 420 is a thin sheet structure. A circular connection through hole 421 is formed on the limiting support piece 420. The support bushing 430 is a circular bushing, and the support bushing 430 is coaxially fitted in the connection through hole 421 so that the limiting support piece 420 is sleeved outside the support bushing 430. The rotating shaft 410 is inserted into the support bushing 430 and the rotating shaft 410 can rotate relative to the limiting support piece 420.

[0038] Specifically, the rotation of the rotating shaft 410 relative to the limiting support piece 420 can be realized by the rotating shaft 410 rotating and fitting with the support bushing 430 and / or the support bushing 430 rotating and fitting with the connection through hole 421.

[0039] Each roller tube 100 includes a first tube section 110 and a second tube section 120. The first tube section 110 and the second tube section 120 are coaxially arranged on opposite sides of the limiting support piece 420. The separately arranged first tube section 110 and second tube section 120 facilitate the assembly of the roller tube 100 on opposite sides of the limiting support piece 420. Correspondingly, the roller leather sleeve 300 outside each roller tube 100 is also divided into two sections, and the two sections of the roller leather sleeve 300 are respectively connected to the outside of the first tube section 110 and the second tube section 120.

[0040] Specifically, one end of the rotating shaft 410 extends out of the connection through hole 421 and is connected to the first tube section 110, and the other end of the rotating shaft 410 extends out of the connection through hole 421 and is connected to the second tube section 120. Thus, by passing the rotating shaft 410 through the connection through hole 421 to connect the first tube section 110 and the second tube section 120, the rotational connection between the roller tube 100 and the limiting support piece 420 is realized. By supporting the rotating shaft 410 with the limiting support piece 420, the rotational support for the roller tube 100 is realized. The support bushing 430 is installed in the connection through hole 421 of the limiting support piece 420 to replace the traditional bearing, and the rotating shaft 410 passes through the support bushing 430. The support bushing 430 is simple to process, can reduce the axial thickness of the support bushing 430, thereby reducing the gap between the first tube section 110 and the second tube section 120, and further reducing the gap between the two sections of the roller leather sleeve 300 connected outside the first tube section 110 and the second tube section 120. When pulling the fabric, the force on the fabric is consistent, and the fabric is beautifully formed.

[0041] In this embodiment, a circumferential annular limiting groove 431 is formed on the outer side of the support bushing 430 along the circumferential direction, and the inner wall of the connecting through hole 421 is embedded in the limiting groove 431, so that the limiting support piece 420 is axially limited on the support bushing 430, preventing the support bushing 430 from moving up and down on the limiting support piece 420, and making the installation between the support bushing 430 and the limiting support piece 420 more firm and reliable.

[0042] Specifically, referring to Figure 5 and Figure 6 , the support bushing 430 includes a first limiting ring 432, a connecting sleeve 433 and a second limiting ring 434 which are coaxially connected. The connecting sleeve 433 passes through the connecting through hole 421. The first limiting ring 432 and the second limiting ring 434 are respectively located on opposite sides of the connecting through hole 421. The first limiting ring 432 and the second limiting ring 434 are spaced apart to form the limiting groove 431 for limiting the limiting support piece 420.

[0043] Among them, the first limiting ring 432 and the connecting sleeve 433 are integrally formed for fixed connection. An annular step 435 is provided at one end of the connecting sleeve 433 away from the first limiting ring 432. The second limiting ring 434 is fitted with the annular step 435. Thus, when installing the support bushing 430, the connecting sleeve 433 can be passed through the connecting through hole 421 and then the second limiting ring 434 can be fitted with the annular step, which is convenient for connecting the support bushing 430 and the limiting support piece 420.

[0044] In this embodiment, the support structure 400 further includes a wear-resistant sleeve 440. The rigidity of the wear-resistant sleeve 440 is greater than that of the support bushing 430. The wear-resistant sleeve 440 is coaxially sleeved outside the limiting groove 431, and the outer side of the wear-resistant sleeve 440 contacts the inner wall of the connecting through hole 421. A wear-resistant sleeve 440 with greater rigidity is coaxially sleeved outside the support bushing 430 to protect the support bushing 430 through the wear-resistant sleeve 440, so that the relatively thin limiting support piece 420 is not easily worn or cut through the support bushing 430, ensuring the service life of the support structure 400.

[0045] Preferably, the support bushing 430 is made of plastic, which has low price and good plasticity, facilitating the manufacturing and forming of the support bushing 430. The wear-resistant sleeve 440 is made of materials such as iron, stainless steel or copper, and has relatively high strength and stiffness, which can effectively protect the support bushing 430 and prevent the limiting support piece 420 from wearing the support bushing 430.

[0046] Referring to Figure 7 and Figure 8 , the bracket assembly 200 contacts the upper side of the limiting support piece 420. One side of the limiting support piece 420 facing the bracket assembly 200 has a support surface 422, and the limiting support piece 420 supports the bracket assembly 200 through the support surface 422.

[0047] Among them, a stop portion 423 protrudes from the outer edge of the support surface 422 (i.e., the edge on the side where the limiting support pieces 420 of the two computerized flat knitting machine rollers 1000 face away from each other). The inner edge of the support surface 422 (i.e., the edge on the side where the limiting support pieces 420 of the two computerized flat knitting machine rollers 1000 face each other) slopes downward from the direction away from the stop portion 423 to form a limiting surface 424. The stop portion 423 and the limiting surface 424 jointly limit the rotation range of the bracket assembly 200.

[0048] Specifically, the blocking portion blocks the bracket assembly 200 on the outside to limit the maximum angle of the opposite movement of the bracket assembly 200 and the roller leather sleeve 300. The moving space between the stop portion 423 and the limiting surface 424 is larger than the size of the bottom of the bracket, so that the bracket assembly 200 can swing at a certain angle between the stop portion 423 and the limiting surface 424, so as to cooperate with the closing and opening between the front and rear rollers.

[0049] In this embodiment, the bracket assembly 200 is provided with a swinging groove 210, and the opening of the swinging groove 210 faces the upper side of the limiting support piece 420. The support surface 422 is inserted into the swinging groove 210 and abuts against the bracket assembly 200. Among them, along the axial direction of the roller tube 100, the width of the swinging groove 210 is greater than or equal to the thickness of the limiting support piece 420. The stop portion 423 and the limiting surface 424 are correspondingly arranged on both sides of the support surface 422, and the support surface 422 fits against the inner end surface of the swinging groove 210, so that the support surface 422 supports the bracket assembly 200.

[0050] In this embodiment, the upper end surface of the support surface 422 is a flat surface, and the bottom wall of the swinging groove 210 facing the limiting support piece 420 is also a flat surface. The support surface 422 fits and abuts against the bottom wall of the limiting groove 431. Thereby, the bracket assembly 200 is further limited to prevent it from swinging excessively towards the side of the stop portion 423.

[0051] A connecting seat 450 is detachably connected to the bottom side of the limiting support piece 420. The limiting support piece 420 is fixedly connected to the needle bed base through the connecting seat 450 to keep the limiting support piece 420 in a fixed state relative to the textile equipment, which is beneficial to the support of the roller tube 100 by the limiting support piece 420.

[0052] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
